To all whom t may concern;

Be it known that LJOi-Iiv CLERMoN'r, a Acitiaejn off the United States, and residentfof the boroughand county of the Bronx,- city and State of New York, haveinvented eertain new and useful Improvements in Attachments for Windows and the like., vof which the following is a specification,

invention relates ,to'windo-ws which' Vthe sashes are capable a pivotal `mevc-ament and to other elements which are hinged or pivoted and has for` its object to provide an attachment which may be positioned to vautoma ically cooperate with a relatively fined element forthe purpose `O15-arresting the pivetal movement of the sash orthe like at predetermined points and which may be brought to an inoperative position when a freeand unrestricted pivotal movement of 1tll Sasher thelike is desired. Y

improvement valso contemplates constructing the attachment in such a manner that the same can be moved to and from its automatically operative position preferably by authorized persons thus protecting the same against tampering and undesired manipulationf i @ther .objects of my invention will appear from the description hereinafter andthe features of novelty will be pointed out' in the appended claims. Reference `is to loe had to the accompanying .drawings which by wayof example illustrate ymy attachment as applied to window having sliding sashes capable of swinging on horizontal pivots under certain conditions.

In the said drawings Figure 1 is a front elevation 'of a window including' my attachment with partsin section; Fig. 2 is av section thereof on the line 2-2 of Fig. 15 Fig.'

3 is a similar view showing the sash` swung on its pivots relatively to the casing; Fig. isV an enlarged detailsectional view of ene ofthe reciprocating stays forming part of the attachment; Fig. 5 is a section thereof on the line of Figrfl; Figs G and 7 are faee and edge views respectively of one of the .cam plates adapted to cotiperate with the stays;` and Fig. 8 is a detail view of oneform ofA device 4or key for moving the reciprocating` stay to and from an operative position; Fig. 9 is a face view of said key in use as a chainelamping device; Fig. `1.0 is a sectional frontelevation ef a window showingsaid As shown in the illustrated example the sashes 10 are pivotally connected at 11 for instance with blocks 12 secured to one end of V .thwsash Mchains or cords 13 and vertically slidable in the Vcustomary grooves 14: located in the casing. lfso'that said sashes in .addition to Vtheir vertical sliding movements are capable .of 'a pivotal movement in vertical planes or in other V'words on` the horizontal pivots 11 under certain conditions. in the example shown the chains 13 of each sash pass over pulleys 13 in pairs to one side of the casing 15 `and have their free ends suitably 'secu-red to a single sash weight 13b or to .other counterbalancing means. With this arrangement the chains of one sash both pass to theright and the chains of the other sash pass to the left and each sash is balanced by a single weight or byothersuitable counterbalancing means.. AIn the drawing only the chains and weight of the lower sash are illustrated for the sakeo-f Clearness. rlfhe said sashes are normally maintained in their vertical ypaths in any suitable manner, -the illustration showing locking strips 16 for nor- 'mallylocking the lower sash against pivotal movement when in its lowered position while l a similar movement of the upper sash in its i'aised position is prevented by parting' strips 17, the said locking strips 16 being movable to an inoperative position to permit a pivotalmoyement of the lower sash when desired. "I will describe my attachment as combined .with :the lower sash only for the purpose of simplicity of description it being understood that the attachmentl may be readily combined with the upper sash or with other more or less similarly movable elements if this should be desired. A

My improved attachment as shown in the drawings comprises a steel or ethei` metallic casse 18 forming part ofor secured to -a plate 19 provided with an aperture 20. A bridge pin 21 is secured to the inside wall of the `case 18 andv projects therefrom into the bore of a tubular sleeveiQ)J which in turn extends exteriorly of the case 18 throughthe aperture`20, and is provided with spaced annular flanges 23, The bridge pin 21 has a sliding Vfit with the bore of .thesleeve 22 while the louter,dialvlfletel of thelatter such as to trated in Fig. 11.

similarly fit the-aperture 20 so thatsaid said sliding movement of said sleeve 22 for f the purpose to be more fully described here-` inafter. Ai'esilient stay arm 24 preferably of spring steel or other suitable inateiial is rigidly secured to the 'sleeve 22 eXteriorly of ythe case 18 and at itsv free end carries abutton head 25 of steel or the like and connected with the arm 24 by means of ashank 26 as clearly` shown in Fig. 4. A steel collar 27 surrounds the sleeve 22 between the flanges 23v and has its free'eiids connected by means of a pin or the like 28 adapted to lit into the forked or notched end 29 of a cam 30 rotatably mounted in the case 18 on trunnions 31,V the common axis of the latter extending transversely to the axis of the sleeve 22.V The cam 36 is formed at opposite corners with recesses or notches 32 adapted to receivethe nose or projection 33 of a counter? acting spring 34% the free ends of which are set in opposite corners of the case18 as illus- The attachment further includes a Vcam plate 35 of steel or the like provided with a slot 36 open at one end andy preferably provided with a vertical face 37 to form a wide mouth at said open end as Y shown in Fig. 6. The said slot 36 comprises a portion 38 arranged at an angle to the vertical path in Vwhich the sash travels and inclined downwardly from said open end.

The portion 38 communicates with a con.-

tinuiiig vertical `portion 39 the `latter in turn being connected with a continuing inclined portion a() terminating in a seat or closed lower end 11. j. A resilient tongue or clip 12 preferably stamped from the plate 35 eX- tends outwardly from and in registry with the lower end portion of said slot 36` as clearly shown in Figs. 6 and 7 and forms a pocket 43 as'clearly shown in Fig. 7.

In utilizing the attachment in connection with a window the plate 35 is rigidly secured at the proper point to an inside vertical surface of the window casing 15 by means of screws or the like with the open end of thc slot 36 projecting upwardly and toward the groove lt'in said casing. The case 18 on the other hand is set into a recess j 39 formed in the adjacent vertical side'edge ofthe sash 10 and the plate 19 is secured thereto by means of screws or other fastening devices adapted to extend through apertures 45 whereby the case, stay arm and connected parts are fastened to the sash so as to be movable therewith. Vith this arrangeinent it will be seen that the cani-plate 35 is stationary or fixed relatively to the-stay arm 21 and its connected parts. The sash is further provided with a depression L16 extend! ing Vupwardly from the recess 39 inn the'said A side edge for the accommodation of the stay arin`21, said recessand depression being'so proportioned as to depth that no part of said stay arm 2-1 projects beyondthe side edge of said sash in the retracted or inoperative position of tliesejparts of the attachment. 1n this condition of the parts the button-head 25 and its shank 26 will move in a plane or path to'one side of or out of Y registry with the plane in which the plate 35 is fixed on the casing`15 so thatthe' sash 1U may be freely swung on its pivots 11 whenV the locking strips 16 are` moved to an inoperative position.

To secure the desired automatic coper ation between the elements of my attach;-V

meiit carried by the sash lO and the part thereof located on the casing 15 it is necesj saryto move the stay arm 24 iii a direction away from the case 18 in order to bring the buttoii-head25 and its shank intoa position where they `will automatically coperate with the plate 35 and its slot 36 at the proper time to arrest 'ainoveinent of the sash 10 on its pivots 11. In order that this may be ac-` complished any'suitable means may be provided; for instance 1 may. provide the earnV 30 with anangular axial opening or recess 47 located in registry withl a similar openingV in the case 18 andV adapted to receive the angular end 418 of ,a key 9 having anV operating handle 50 preferably terminating in la forked projection 51 extending at an angle thereto. This angular end 48 isadapted to be inserted into the angular opening 'or rer-V cess {LZ after which the key 49 is rotated in owing to its connectioiiwith the pin 28 and collar V27 will slide or move the" sleeve 22- along the bridge pin 21 also toward the right in said Fig. 4, theinose or projection 33 of the spring 3% being forced'out of the one notch 32 of the cam 30 and finally snapping into the other notch 32 to secure said cam and its connected parts in the adjusted kposi tion. In its movement along the bridge pin 21 as described the sleeve 22 carries with it the stay arm 211 and thus inoves the latterl away from the window sash! 15 and into the Y groove 11 of the window casing 15 so that the shank 26 of the. button-head 25- is now in the saine plane with' the. slot 36 ofthe plate 35 or in other words said slot is in the i If the sash 15 is now' swung on its pivots 11. out of the casing, the

path of said shank.

strips 16 having been previouslyopenedto permit this, the said Shank '26 Will at the proper time enter the slot 36 and travel of the head and shank in a reverse direction out of the slot will be prevented. As the said shank 26 and head 25 thus move into theslot and become seated therein the free end of the stay arm 2lwill be held and said arm will describe a pivotal movement on the pin 21 relatively to the case 18 and sash 10 as the latter is pivotally swung and will thus arrest -said pivotal movement of said sash and firmly hold it in'an inclined position relatively to the window casing' 15. 1n this position of the parts a space exists between the upper and lower sashes through which air enters and passes out thussecuring perfect ventilation without anydirect drafts. The attachment also permits the lower `edge of the sash to be raised to produce a space between said lower edge and the window sill whereby double ventilation may be secured if desired. At the same time the attachment also prevents the accidental complete discharge or free pivotalmovement of the sash in case the locking strips 16 should be accidentally left in their lopen or` inoperative positions. j Y y To return the sash to its normal upright position in the casing it is only necessary to bring the sash to its lowermost position and then exert a suilicient pressure thereon toward said casing to overcome'the tension ex'- erted by the clip 12 on the headV 25 and thus cause the shank 2 6 to move lengthwise of the slot "With the shank 26 inthe seat 41 of the slot 36 and the sash swung out of the casing and in its lowermost position therein the arm 2liextends downwardly at a more or less acute angle to the inclined walls of the portion e0 so that the shank 26 is readily moved along the same and lengthwise of the slot toward its open end as pressure is exerted on the sash toward the casing as described. This operation will finally move the shank 26 out of the slot 36 and cause the head 25 to contact with a wall of the groove 141- along which said head 25 will travel as the pivotal movement of the sash 10 in the reverse direction is continued and thus cause the arm to return to its normal upright position. Tilfith the lower end of the sash slightly raised from the sill in the outwardly swung position of said sash, the arm 211 will extend perpendicular to the walls of the portion L10er upwardly at a more or less obtuse angle thereto. if pressure as above described is exerted to swing the sash into the casing when lin this raised position the shank 2G will .be forced against the walls of said portion #10 and a further inward movement of said sash thus arrested or said shank 26 will be forced more :firmly into the seat l11 with the same result. This arrangement thus absolutely prevents the sash from being swung into the casing when inV anything other than the proper coperative position therewith and prevents the one sash from smashing into and damaging the other.` 1n other words the device is rendered absolutely fool proof and .proper cooperation is absolutely assured.

The parts are so positioned on the window casing and' window sash respectively that a cooperative engagement of one with the other is assured each time Vthe sash is pivotally moved and providing the stay arm 24s is in its outward position so that an absolutely automatic action is absolutely guaranteed. lNhen a complete or free pivotal movement of the sash 10 is desired the end 4S of the key 49 is simply inserted into the aperture 4:7 and the handle 50 is prop- Verly actuated to operate the' cam 30 in a direction to slide the sleeve 22 toward the left in Fig. 4, this operation forcing the nose 33 of the spring 3% out of the right hand notch 32 and causing it to finally snap into the left hand notch 32 of the cam 30 when the final retracted position of the parts has been reached. The actuation of the sleeve 22 as j ustl described will also move the stay arm in the same direction and return it into the depression #i6 in which condition the arm as well as the head 25 lie entirely within the confines of' the sash and out of the planein which the slot B'Gis located. 1f' the locking strips 16 are now moved to an open or inoperative position the sash 10 may be freely swung to any position within its limits of oscillation and may thus for instance be readily and easily cleaned without making it necessary for the cleaner to step outside of the window. By placing the keys only in the possession of authorized persons and by having the parts normally in their outer position so that the plate 35 is normally always in the path of the shank 26 and head 25 the danger of accidental complete pivotal movement of the sash out ofthe casing and resulting injuries are absolutely prevented and the complete pivotal movement of the sash is possible only after the parts have been adjusted described by these authorized persons with the aid of the said keys. The counteracting spring 34C is so arranged that an attempt to move the arm 2li to an inoperative position by exerting a pressure toward the sash therein will be completely counteracted. This is due to thefact that the free end portions of the spring at opposite sides of the projection 33 lie in substantially straight lines between said projection and the corners of the case 18 when the projection is in either notch 32 and thus absolutely prevent any movement of the cam excepting with the assistance of the properl key as will be clearly apparent.. The attachment is thus positive in its operations and completely safeguarded against tampering by unauthorized persons, it being under- Astood that other more complicated devices may he substituted for the key and key hole construction .shown in the illustration to still further guard ag-ainst such contingencies. The key 49 in the illustrated form may also be used as a means for locking the chains 18 and sash weights 13b when it is desired to completely remove a sash from the casing. For this purpose the window casing 15 is provided at a suitable point with a recess 15 adapted to receive the key/19 and end 4S thereof in such a manner that the handle 50 will extend lengthwise of the casing 15 and the forked projection 51 will project at an angle thereto. By simply inserting one of the chains 13 of the sash which is to be removed into the forked projection 51 as shown in Figs. 9, 10 and 11 the said chain will be firmly held and the cooperating weight 13b thus secured against dropping. The particular sash 10 may now be swung clearpof the casing 15 and the pivots 11 detached therefrom to permit the complete removal of said sash, the chains 13 and weight 13b being meanwhile securely held by the key 50 thus permitting an uncasing. The key may however be similarly used for the purpose described in connection with windows hung and counter-balanced in .the ordinary way.

In describing the attachment I have referred to the same in the singular although in practice I prefer to provide duplicate parts at the two opposite vertical sides of the window, it being evident however, that in some cases a single attachment located at one side thereof1 will be sufficient to secure the intended results. In addition to this it will be readily apparent that the attachment is not limited to use in connection with windows and that the same may readily be combined with other movable elements when a limitation of movement in a certa-in direction is desired as for instance in doors and the like.

Various changes in the specific form shown and described may be made within the scope of the claims without departing from the spirit of my invention.
